Mahr is trusted by a renowned industrial organization to provide accurate measurements of gears for aircraft engines. Mahr’s MarSurf Engineered Series 1300 can assess the roughness of double helical gears with high accuracy and dependability.
The highest criteria must be met by the gears used in airplane engines. The measurement information must be accurate and must not endanger the workpiece. Two more requirements had to be satisfied when Mahr learned about the unique task of a renowned industrial company: It was necessary to increase the measurement time’s effectiveness and the gear roughness machine’s quality. In order to prevent human mistakes and save time, Mahr needed to create a measuring system that wouldn’t harm the helical twin gears while also automating the previously manual procedure. When Mahr’s project manager assumed control of this work, he was perfectly aware of how to resolve the issue and completely satisfy his client.
Introduction of a new measuring concept: skidless tracking.
The data from the prior measuring solution varied depending on the operator and, occasionally, the measured double helical gears were physically harmed during the measurement and were unable to be provided. The gear was clamped and rotated during the measurement, which explains why. As a result, the workpiece is subjected to clamping forces that may cause damage. The right answer was there in front of Mahr’s project manager, who recommended rotating the probe while the workpieces were being straightened rather than moving them. He then unveiled the skidless probing-based MarSurf Engineered Series 1300: The gear itself does not move; instead, the driving unit rotates to align itself with the gear’s angle. The MarSurf Engineered Series 1300 could also be employed as a fully automated system, giving the business all the benefits it had hoped for.
MarSurf Engineered Series 1300: easy to use
The customer did not regret selecting Mahr Engineering Solutions’ unique solution. The gearbox was formerly fixed to a locator. This made mounting it in the same location challenging and time-consuming. The MarSurf Engineered Series 1300 has altered this. Even the procedure is simpler now. A variety of gears can be measured fast and easily thanks to the specialized gear measurement software. The measurement sequence is determined based on the relevant gear data (such as the number of teeth, diameter, module, and angle of the helical teeth), which simply has to be entered. The driving unit is adjusted by the corresponding helical gear angle after beginning the utility software, and the machine then automatically establishes the starting point and initiates the measuring process. The operator only conducts a visual examination. The measurement can be performed without any metrological expertise, measuring station-specific information, or programming expertise.
From 2 hours to 8 minutes measurement time
Once the company started measuring with the MarSurf Engineered Series 1300, the benefits became obvious: with the fully automated measurement of the S 1300, the stability of the measurement results was improved and the measurement time was reduced from 2 hours to 8 minutes. This allowed the company to recoup its investment in the S 1300 within 2 years. With this innovative technology, Mahr has helped its customer overcome its challenges and ensure the highest quality of double helical gears for aircraft engines.
